adding vent to fuel filler tube ??

Post by Stan » Sun Jan 18, 2015 12:04 pm

I want to add a vent to the aux tank filler tube. I installed a new tank 8-10 years ago so it has an outlet for it but the aux tank filler on 68s didn't have a vent.
Anyone done this ? I'm thinking maybe a short piece of steel fuel line , flared at one end {flare on inside of filler tube} then weld . Is the filler tube thick enough to weld?
Or maybe a threaded flared nipple. Drill the correct size hole in the filler tube to thread the nipple into and then braze it ?
Seems in my travels I've seen a "compression type outlet " - drill a hole - the "outlet fitting" is flared and uses a curved gasket and washer on each side , threaded on outside with a nut to tighten and make a compression seal. hmm - but would have to be impervious to gasoline.
Any - ideas ?

why not change the whole filler tube to a newer model that has a vent tube on it ?
most people are absent,,, my merciful nature, and sense of fair play !

That is one option. The new ones the vendors sell use the "longreach" style gas cap. No real problem and would work and i dont think there would be much visual difference . But I would have to buy new gas cap or caps. Currently have 2 Stainless caps and only found chrome in the long reach caps. So new - $70-$75 - one of the cheaper EB projects. :) . Another minor issue is the existing filler tube painted to match the Bronco - but again - nothing major .
Another option is to see if I could find an " original " filler tube from newer model laying around in someones xtra parts pile.
Just enough little things to make me think - " I gotta take the filler tube out either way " - sooo -

Yep - that counts. :) But it Could make for a good " dumbass tv ' video - especially if a guy was dumb enough not to move it outside of the garage before welding.

are you set up to weld stainless?? seems like the filler neck was stainless. i could be wrong it would suck to be wrong this early in the year. but then being right the rest of the year sounds good also.

I'll have to check on that BEFORE I drill a hole in the filler tube.
I talked to one guy who said he welded his and another who said he brazed one -- but I didn't get all the details yet.

Hmm - ya I can probably make my own " compression fitting" . Save me the trouble of trying to weld that thin stuff without blowing thru.

Only in case you're wondering ;
Brazing turned out to be the best and easiest way to do this.
The filler tube wasn't stainless - at least not on the '68.
And unlike some projects - it was worth the effort. :)

LOL - I coulda dressed it up a little before photo - but hey who's going to notice.
I also found /used a 90* brass fitting and got it to seal { as per Arsenio} but in the "sense of adventure " decided to braze it . I haven't done any of that in 40 years so thought I'd see if I could still do it. LOL - not as steady as I used to be and sure can't see as well - but it was fun. I did some practicing with different heat sources and brazing rods - just for the Hell of it. :)

Have you got that thing back together? Was curious if it takes fuel any faster.

Yes it does take fuel better - bout like the stock one -ok but not great. LOL
If I did another one I'd use a little bigger tubing for the vent and " clock " it a little more toward the front of vehicle. I put this one in the same as the one on the 76.

I've got a hood , tailgate ,two fenders I was going to make a cover for my BBQ or garbage can.
Hmm - if we knew someone creative we could consolidate some of these parts and make some type of" yard art" or some type of portable bbq/ice chest combo .
